最有效的WordPress禁止生成缩略图教程

一开始使用最传统的方法禁止，在设置里面把图片尺寸全部设置成0以及进入所谓wordpress上帝模式设置，测试后发现该生成的还是生成根本没有效果，把以下代码加入你的主题 functions.php 文件即可。

// 禁用自动生成的图片尺寸
function shapeSpace_disable_image_sizes($sizes) {
    
    unset($sizes['thumbnail']);    // disable thumbnail size
    unset($sizes['medium']);       // disable medium size
    unset($sizes['large']);        // disable large size
    unset($sizes['medium_large']); // disable medium-large size
    unset($sizes['1536x1536']);    // disable 2x medium-large size
    unset($sizes['2048x2048']);    // disable 2x large size
    
    return $sizes;
    
}
add_action('intermediate_image_sizes_advanced', 'shapeSpace_disable_image_sizes');
 
// 禁用缩放尺寸
add_filter('big_image_size_threshold', '__return_false');
 
// 禁用其他图片尺寸
function shapeSpace_disable_other_image_sizes() {
    
    remove_image_size('post-thumbnail'); // disable images added via set_post_thumbnail_size() 
    remove_image_size('another-size');   // disable any other added image sizes
    
}
add_action('init', 'shapeSpace_disable_other_image_sizes');
